Скачать или смотреть The Birthday Problem (Part Two): Programming in R

In this second video, we turn the code from Part One into a function in R, look at iterating using map rather than a for loop, and combine the results with ggplot while looking to investigate what happens if we change the assumptions of the Birthday Problem - looking at a realistic distribution of birthdays rather than assuming an equal distribution.
